clean air-conditioning condenser in time, if the congestion will affect air conditioning refrigeration effect, if too dirty, condenser bushing manufacturer recommendations with water cannons to wash and clean. Regularly check the belt tension of air conditioning compressor, usually once every 250 hours inspection, belt tensioning degree should be around 10 mm, if the belt too loose not only noise but also can appear the phenomenon of sound, refrigeration effect is poor. Need to regularly check refrigerants, refrigerant liquid level height, also affects the cooling effect of air conditioning, Normal pressure low pressure 1. 5 - 2 kg/cm2 pressure - 13 17kg/cm2) 。 About the air conditioning maintenance: ( 1) When the air-conditioning outlet air volume with using gradually reduce, please inspect the air conditioner filter blockage and cleaning, daily vehicle driver, please often give cleaning and inspection, when it is necessary to replace the new air conditioner filter.
